For a Privoxy regression test I'm trying to send a POST request slowly. I'm experimenting with <command>s like: --limit-rate 1k -d "blafasel%repeat[5000 x padding]%" http://%HOSTIP:%HTTPPORT/%TESTNUMBER
Unfortunately the Privoxy log indicates that the whole request always arrives within a second. This is reproducible without using Privoxy as proxy. Apparently the rate limit only kicks in after the request has been sent and as a result the (small) response is then received delayed. The attached patch (gzipped to preserve line endings) adds a test that reproduces the two related issues.
